Variable Costs
Business expenses that change in direct proportion to production volume or business activity.
Definition
Variable Costs fluctuate with the level of production or sales activity. As you produce or sell more, these costs increase proportionally. As production decreases, variable costs decrease. This makes them flexible but directly tied to business volume.
